Forests – just how absorbing are they?

14.03.2003


Forests form an integral part of the Kyoto Protocol on climate change because they act as terrestrial “sinks” to soak up the carbon emissions that are contributing to global warming. Countries that have ratified the protocol can offset their carbon emissions quota by planting trees, either at home or in developing countries. But how efficient is this “carbon trading” and how good are forests at absorbing these extra carbon emissions?



Nearly one hundred of the world’s leading experts on global warming will gather in Southampton from 1-4 April 2003 to share the results of their latest research on the role that forests can play in mitigating climate change. Bob Watson, Chief Scientist of the World Bank – the body overseeing global carbon trading - will open the symposium by examining the key part that ecology plays in global policies to ameliorate climate change.

Professor Howard Griffiths of the University of Cambridge will tell the symposium: “The remit for plant scientists is a hefty one. Not only do we need to quantify the capacity of global terrestrial carbon sinks, but we also need to critically assess the methods and models we use to make sure that our measurements are accurate and reliable enough to predict likely future levels of carbon.”


Speaking at the symposium, Professor John Grace of the University of Edinburgh and President of the British Ecological Society will highlight the complexity of the carbon cycle, understanding of which is crucial for predicting and reducing the impact of climate change. According to Professor Grace: “The challenge is to predict the behaviour of carbon cycles over the next few decades. There are substantial gaps in our capacity to conduct adequate surveillance, as well as in our knowledge of how the carbon cycle works.”

Im Focus: The taming of the light screw

DESY and MPSD scientists create high-order harmonics from solids with controlled polarization states, taking advantage of both crystal symmetry and attosecond electronic dynamics. The newly demonstrated technique might find intriguing applications in petahertz electronics and for spectroscopic studies of novel quantum materials.

The nonlinear process of high-order harmonic generation (HHG) in gases is one of the cornerstones of attosecond science (an attosecond is a billionth of a...

Im Focus: Magnetic micro-boats

Nano- and microtechnology are promising candidates not only for medical applications such as drug delivery but also for the creation of little robots or flexible integrated sensors. Scientists from the Max Planck Institute for Polymer Research (MPI-P) have created magnetic microparticles, with a newly developed method, that could pave the way for building micro-motors or guiding drugs in the human body to a target, like a tumor. The preparation of such structures as well as their remote-control can be regulated using magnetic fields and therefore can find application in an array of domains.

The magnetic properties of a material control how this material responds to the presence of a magnetic field. Iron oxide is the main component of rust but also...

Im Focus: Self-healing coating made of corn starch makes small scratches disappear through heat

Due to the special arrangement of its molecules, a new coating made of corn starch is able to repair small scratches by itself through heat: The cross-linking via ring-shaped molecules makes the material mobile, so that it compensates for the scratches and these disappear again.

Superficial micro-scratches on the car body or on other high-gloss surfaces are harmless, but annoying. Especially in the luxury segment such surfaces are...

Im Focus: Stellar cartography

The Potsdam Echelle Polarimetric and Spectroscopic Instrument (PEPSI) at the Large Binocular Telescope (LBT) in Arizona released its first image of the surface magnetic field of another star. In a paper in the European journal Astronomy & Astrophysics, the PEPSI team presents a Zeeman- Doppler-Image of the surface of the magnetically active star II Pegasi.

A special technique allows astronomers to resolve the surfaces of faraway stars. Those are otherwise only seen as point sources, even in the largest telescopes...

Im Focus: Heading towards a tsunami of light

Researchers at Chalmers University of Technology and the University of Gothenburg, Sweden, have proposed a way to create a completely new source of radiation. Ultra-intense light pulses consist of the motion of a single wave and can be described as a tsunami of light. The strong wave can be used to study interactions between matter and light in a unique way. Their research is now published in the scientific journal Physical Review Letters.

"This source of radiation lets us look at reality through a new angle - it is like twisting a mirror and discovering something completely different," says...
